Specification of Letters Patent.

Patented Mar. 14, 1922.

Application filed January 12, 1921. Serial No. 436,888.

To all whom it may concern:

Be it known that I, CLIFFORD H. RAMSEY, a citizen of the United States, residing at Glen Rock, in the county ofBergen and State of New Jersey, have invented certain new and useful Improvements in Mangles, of which the following is a vspecification.

This invention relates to machines for treating sheet material and particularly fabrics with liquids, assizing liquids, by passing them between rolls, called nip rolls one of which is made in some way to carry on its surface and to the sheet the liquid of treatment, as by contacting with a pick-up roll which dips into a container for the liquid. In these machines the several rolls are held pressed against each other and the pick-up roll and adjoining nip-roll are geared together so as to rotate at the same surface speed, and heretofore they have been gearedtogether directly (by a gear on one intermeshingwith a gear on the other), in consequence of which proper intermeshing of their gears endures only so long as the diameter of the rolls remains in the original proper proportion to that of their gears, and if the rolls undergo reduction in diameter for any reason, as from wear or re-surfacing them, the intermeshing co-action of the gears will be faulty. One object of the invention is to provide a gearing connection between the said rolls wherein a good intermeshing co-action will be maintained though the diameter of the rolls changes for any reason. Another object is to provide means whereby a micrometer adjustment of the spacing of the several rolls may be effected and accurately preserved and yet the rolls left free for movement away from each other for any purpose, as in introducing the goods between the nip rolls at the beginning of a treatment.

In the drawings, Figure 1 is a s1de elevation of a machine, known as a quetch and employed for treating fabrics with liquids, embracing my invention;

Figure 2 is a section on line 2-2, Figure 1;

Figure 3 shows the improved gearing as seen from the left in Figure 1; and

Figure 4 is a section on line 4--4=, Figure 3.

The frame a of the machine includes a pair of uprights b and at the ends thereof suitable bearings c for the trunnions d of the beams e on which the material A to be treated 1s wound. It will be understood that the material A comes to the machine wound on one beam e and upon having its free end attached to the other beam the latter is rotated by suitable means to advance the mater al lengthwise and wind it on said latter beam; and. that after the material has thus been wound from one beam to the other the operation may be reversed. f designates a panor other receptacle holding the liquid of treatment, as size.

g, h and 11 respectively designate the pickup roll and the lower and upper nip rolls. The roll 9 is journaled in fixed bearings j on the frame. The rollers h and z are journaled in pairs of levers 7c fulcrumed one above the other on suitable studs} adjustably set in vertical slots min the uprights b. The levers is, which are fulcrumed between their ends, have on their said ends weights n which are adjusted so that the roll it is normally urged toward the roll 9 and the roll i toward the roll it with that pressure which is requisite for causing the roll 9 to deliver liquid to the roll it and the rolls h and i to exert the desired compression on the material A, according to the nature thereof and other considerations, the limit of movement of the rolls 7:. and i in the direction in which they are thus normally urged-being determined by certain micrometer adjustment means to be set forth."

0 designates suitable elevatory means for moving the levers is contrary to the direction in which they are normally urged whenever it is necessary for any reason to interrupt their pressure coaction with each other.

Roll 2' is driven by the material A as an incident of its frictional contact with roll h. Roll. 9 is positively driven by any suitable means (not shown). In practice it is found thati-the frictional contact between the rolls 9 and h is not sufiicient to transmit rotation to the roll it from roll 9 (at least constantly and at the same surface speed, which is desirable in order to produce an even distribution of the sizing liquid over the surface of roll h and hence on the fabric), and so it is customary to connect these two rolls by gearing, usually consisting of two gears on the rolls g-k which intermesh when the rolls are together. Instead of such gearing I place on the rolls 9 h non-intermeshing gears 12 q and on two levers? s, which are fulcrumed coaxially with, as on the shafts of,

the rolls 9 h and are pivoted together at t, transmission gears 11- 21, which mesh with each other and with gears p g, respectively, one of the transmission gears, u, being journaled on the stud t forming the pivot between the levers. By this arrangement in any spacing of the rolls 9 h the gears u v preserve constant relation to the centers of the respective gears p g and gear v preserves constant relation to the center of gear u, so that the original condition of inter-mesh of the gears never alters. By providing only two levers in the lever system carrying the gears u v the construction is considerably simplified, because the levers are self-supporting; if there were three or more levers I in series the system would require special support to prevent its falling and so permitting gear 2) to mesh with both gears p g.

The micrometer adjustment of the spacing of the several rolls is eflected and accu rately preserved so as to leave the rolls free for movement away from each other when necessary, as at the beginning of a treatment when the goods is to be removed, or for changing the rolls, as follows: The structure including each lever is also includes, pivoted to the lever, the fitting w, in the form of a fork which straddles the lever and whose head w has a flat end face and on its periphery an index 10 An adjustable stop for each lever structure is pivoted on the upright, the same in the present instance consisting of a nut 00 pivotally movable on a study 3 projecting from the upright and a threaded shank 2 which is tapped into the nut and has a handle 2 at one end for turning it and an abutment head 3 fixed thereon at a point short of its other end, which is telescoped into the head w of the corresponding fitting w; the abutment head has a dial 3' on its periphery to coact with the index 'w The arrangement is such that having adjusted the weights at on the levers so as to produce the desired downward pressure of the rolls 2' and it, their limit of downward movement (that 1s, the desired center to center spacing of the rolls) may be nicely determined by turning the screws 2; and since the parts '20 and z are telescoped to and hence guide each other the adjustment once obtained will always ensue after the levers have been moved to space the rolls for any purpose.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a machine of the class set forth, the combination of a frame structure, a roll-supporting lever-structure fulcrumed therein and normally urged to move on its fulcrum in one direction, and an adjustable stop on one structure engageable by the other structure to limit the movement of the lever structure in said direction, and including a threaded shank and a nut thereon, said shank freely telescoping said other structure.

2. In a machine of the class set forth, the combination of a frame structure, a roll-supporting lever-structure fulcrumed therein and normally urged to move on its fulcrum in one direction, one of said structures including a pivoted fitting, and an adjustable stop pivoted on the other structure and freely telescoping the fitting and engageable thereby to limit the movement of the lever structure in said direction.
